Long-term Safety and Tolerability of Idalopirdine (Lu AE58054) as Adjunctive Treatment to Donepezil in Patients With Mild-moderate Alzheimer's Disease

Phase 3
Completed
Conditions
Alzheimer's Disease
Interventions
Registration Number
NCT02079246
Lead Sponsor
H. Lundbeck A/S
Brief Summary

To evaluate the long-term safety and tolerability of idalopirdine (Lu AE58054) as adjunctive therapy to donepezil in patients with mild-moderate Alzheimer's Disease (AD).

Detailed Description

This is an interventional, multi-national, multi-site, open-label extension study in patients with mild to moderate AD who completed the 24-week lead-in study 14861A (NCT01955161) or 14862A (NCT02006641).

Patients received 28-weeks of open-label treatment with idalopirdine 60 mg/day (option to reduce to 30 mg/day) as adjunctive treatment to donepezil. Approximately 100 patients, who had completed the initial 28-week period (OLEX), were included in a 24 week open-label treatment period with memantine (OLEX-MEM) that evaluated the safety and tolerability of concomitant memantine therapy in patients who were already on a stable treatment with idalopirdine and donepezil and for whom memantine treatment was clinically indicated.

Inclusion Criteria
  • the patient has completed Visit 7 (Completion Visit) in the lead-in double-blind, placebo controlled clinical studies 14861A/NCT01955161 or 14862A/NCT02006641

For patients in the OLEX-MEM:

  • The patient has completed Visit 6 (Week 28) of the OLEX.
  • The patient, according to the judgement of the investigator, requires initiation of treatment with memantine as per local label/SmPC/treatment guidelines.
Exclusion Criteria
  • The patient has a moderate or severe ongoing adverse event from the lead-in study considered a potential safety risk by the investigator.
  • The patient has experienced seizures before Completion Visit in the lead-in study.
  • The patient has evidence of clinically significant disease.
  • The patient's donepezil treatment is likely to be interrupted or discontinued during the study.
  • The patient is receiving therapy with another acetylcholinesterase inhibitors (AChEI).

Other protocol-defined inclusion and exclusion criteria may apply.

Idalopirdine 60 mg + memantineIdalopirdine 60 mgIdalopirdine 60 mg as adjunct to 10 mg donepezil and memantine (patient's individualised maintenance dose, either immediate-release (IR) 20 mg/day (recommended target dose) or extended release (XR) 28 mg/day (recommended target dose). Memantine was administered to approximately 100 patients included in the OLEX-MEM. The dose of idalopirdine could be decreased from 60 mg to 30 mg if 60 mg was not well tolerated. The dose of donepezil was to be maintained throughout the study. The dose of memantine could be changed at any time throughout the study.

Primary Outcome Measures
NameTimeMethod
Number of Treatment Emergent Adverse Events (TEAEs) in the OLEXBaseline II (start of OLEX, week 0) to end of OLEX (week 28)

A TEAE is an adverse event that starts or increases in intensity after the date of Baseline II.

Number of TEAEs in the OLEX-MEMFrom Baseline III (start of OLEX-MEM, Week 28) to end of OLEX-MEM (Week 52)

A TEAE is an adverse event that starts or increases in intensity after the date of Baseline III (start of OLEX-MEM).

Secondary Outcome Measures
NameTimeMethod
Change in Cognitive Aspects of Mental FunctionBaseline III (start of OLEX-MEM, Week 28) to Week 52

Change from Baseline III to Week 52 in Mini Mental State Examination (MMSE). The MMSE is an 11-item test to assess the cognitive aspects of mental function. The subtests assess orientation, memory, attention, language, and visual construction. The scores for each item is dichotomous (1 = response is correct, 0 = response is incorrect). Total score of the 11 items ranges from 0 to 30 (higher score indicates lower deficit).

Change in CognitionBaseline II (start of OLEX, Week 0) to Week 28

Change from Baseline II to Week 28 in Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-Cog) total score. The ADAS-cog is a 11-item neuropsychological test that assess the severity of cognitive impairment. The items determine the patient's orientation, memory, language, and praxis. Total score of the 11 items range from 0 to 70 (lower score indicates lower cognitive impairment).

Change in Behavioural DisturbanceBaseline II (start of OLEX, Week 0) to Week 28

Change from Baseline II to Week 28 in Neuropsychiatric Inventory (NPI) total score. The NPI is a 12-item structured interview with a caregiver to assess behavioural disturbances. The NPI comprises 10 behavioural and 2 neurovegetative items. Each item consists of a screening question and several sub-questions that are rated no (not present) or yes (present). Each item is rated for frequency (a 4-point scale from 1 \[occasionally\] to 4 \[very frequent\]) and severity (a 3-point scale from 1 \[mild\] to 3 \[marked\]). The total NPI score is the frequency ratings multiplied by the severity ratings and ranges from 0 to 144 (higher score indicates worse outcome).

Clinical Global Impression ScoreWeek 28

Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-CGIC) score at Week 28. The ADCS-CGIC is a semi-structured interview to assess clinically relevant changes in patients with AD. The items determine cognition, behavior, social and daily functioning. Severity at baseline is rated on a 7-point scale from 1 (normal, not ill at all) to 7 (among the most extremely ill patients). The clinically relevant change from baseline is rated on a 7-point scale from 1 (marked improvement) to 7 (marked worsening).

Change in Daily FunctioningBaseline II (start of OLEX, Week 0) to Week 28

Change from Baseline II to Week 28 in Alzheimer's Disease Cooperative Study - Activities of Daily Living Inventory (ADCS-ADL23) total score. The ADCS-ADL23 is a 23-item clinician-rated inventory to assess activities of daily living (conducted with a caregiver or informant). Each item comprises a series of hierarchical sub-questions, ranging from the highest level of independent performance to a complete loss for each activity. Total score of the 23 items ranges from 0 to 78 (higher score indicates lower disability).
